Thank you for viewing. I purchased this at an authorized retailer several years ago. It's lightweight and durable. I'm selling it because I don't have the opportunity to use it. *We do not accept claims or returns after purchase. ■Frequency of use I only took it camping once. I only put it in the car and didn't take it out at the campsite, so it's almost like new. However, it's not brand new, so please refrain from purchasing if you are sensitive to this.
